Just published a WebLN-based demo for PoW Pub: https://lab.oak-node.net/powpub/uv/wasm-client/
Clients can pay Providers to mine them vanity pubkeys. The mined keys are of ocurse only known to the client.
Providers can run a miner in the background on any modern computer. All you need is a LN Address.
